The Fast version of Picokine ELISA kits, assay takes less than 1.5 hours. Detect Rat Fibronectin/FN1 with <15pg/ml sensitivity. Format: 96-well plate with removable strips. Compatible samples: cell culture supernates, serum and plasma(heparin, EDTA, citrate). This is a TMB colorimetric sandwich ELISA kit with short assay time and fast experiment set up. Fibronectin/FN1 tissue specificity: Plasma FN (soluble dimeric form) is secreted by hepatocytes. Cellular FN (dimeric or cross-linked multimeric forms), made by fibroblasts, epithelial and other cell types, is deposited as fibrils in the extracellular matrix. There is no detectable cross-reactivity with other relevant proteins. Sample Types: cell culture supernates, serum and plasma(heparin, EDTA, citrate). Range: 156pg/ml-10,000pg/ml. Sensitivity: <15pg/ml
